CG Semi Private Limited, a joint venture between CG Power and Industrial Solutions Ltd., Renesas Electronics Corporation, and Stars Microelectronics, has started commercial production at its G1 Outsourced Semiconductor Assembly and Test (OSAT) facility in Sanand, Gujarat. The plant has a peak capacity of 300 million units annually.
This operational milestone marks a shift from infrastructure setup to revenue generation. By transitioning G1 from its August 2025 inauguration to active shipping, the venture validates the technical viability of domestic back-end processing.
The Bottom Line
- Capital Outlay: Total investment exceeds ₹7,600 crore over five years for two facilities (G1 and G2).
- Production Scale: G1 is now active with a 300 million unit annual peak capacity; G2 remains under development.
- Strategic Alliance: The venture combines CG Power, Renesas Electronics Corporation and Stars Microelectronics.
How the G1 Facility Impacts India’s Semiconductor Pipeline
The G1 facility is an OSAT site. In the semiconductor value chain, OSAT handles assembly, packaging and testing. According to the company, the site utilizes high-yield production systems and in-house failure analysis to ensure quality readiness for global customers.
While G1 provides the initial proof of concept, the total ₹7,600 crore investment is split across two sites. The upcoming G2 facility is designed to scale capacity significantly once operational. This staggered rollout allows the joint venture to stabilize processes and train Indian engineers.
| Metric | G1 Facility (Current) | G2 Facility (Planned) |
|---|---|---|
| Status | Commercial Production | Under Development |
| Peak Capacity | 300 Million Units/Year | TBD (Scaling Increase) |
| Total JV Investment | ₹7,600+ Crore (Combined) | |
| Inauguration Date | August 2025 | Pending |
Why the Renesas and Stars Microelectronics Partnership Matters
The technical success of G1 depends on the collaboration between Renesas Electronics Corporation and Stars Microelectronics.
CG Semi has invested in training Indian operators and technicians specifically for high-volume OSAT operations. Mr. Vellayan Subbiah, Chairman of CG Power, stated that the first shipment “reflects the enormous belief behind these small chips and the combined effort of a remarkable team.”
This development is backed by central and state government support.
What Happens Next for CG Semi’s Market Position
The commencement of commercial production at G1 moves the venture to a revenue-generating entity. The focus includes the “customer qualification” phase, where global clients verify that the Sanand-produced chips meet industry standards. Success here is the prerequisite for the full-scale rollout of the G2 facility.
By performing assembly and testing locally, CG Power and its partners can serve customers across the globe.
As the G2 facility progresses, the venture’s ability to capture a larger share of the market will depend on its yield rates. High-yield production systems are already in place at G1, but scaling those efficiencies to a second site will be the primary operational challenge.
